Measuring Success

The ISB community and potential parents are understandably interested about the quality of our students’ learning, especially against challenging international standards. Over many years, the school leadership and the Board of Trustees have put into place a number of key performance indicators to ensure that we continue to provide outstanding educational opportunities for all our students. Below you will find a number of indicators that will inform you about school performance.

International Baccalaureate Diploma Results 2018Our IB Diploma candidates from the class of 2018 achieved a mean IB Diploma score of 35 compared to the world average of around 30 points (out of a maximum of 45). The average IB Diploma pass rate for May 2018 was 97% and the mean over the past 5 years is 95% compared to a world average of approximately 79%.

For May 2018:

The average score for successful IB Diploma recipients was 35 and overall the average score for each IB Course was 5.51
17 students achieved a score of 40 or more points with 2 students scoring our highest level of 45 out of 45 possible points
34 Bilingual Diplomas were awarded, (31%)
172 ISB students took one or more IB subjects across 1041 individual IB Courses

Parent Survey

We believe that parent surveys offer useful information to gauge our success in achieving our Mission and in informing our school improvement agenda. To this end, we conduct three types of surveys each year:

In November, we survey parents new to ISB in the past six months.

In December, we survey parents who have left ISB during the previous year.

In May, we survey current parents.

International School Assessment ResultsEvery 3 years, 10,000 students in each of 40 nations take the Program for International Student Assessment (PISA). We administer the International School Assessment (ISA) each year at 3rd, 5th, 7th, and 10th grades. Our scores are compared to those of students from approximately 200 schools in 60 countries.

Because PISA and ISA are related, we can compare our 10th grade ISB students with those in the nations that consistently perform best on the PISA. The table below shows the results from the most recent PISA testing, and compares 10th grade ISB students’ scores to those from the top 4 scoring nations on PISA, and those from the USA.

We also compare the performance of our students on the ISA with those from the 180 International Schools that use this assessment.

This table compares ISB’s mean scores on ISA to the scores of the other international school students in that testing session. For example, in the 2015/16 Grade 3 Math test, the ISB mean score is as good as or better than the scores of 65% of the students in that testing session. This table also shows the average of ISB’s mean scores compared to other international schools for the last 5 years.

Measures of Academic Progress Results

Each September and April/May, ISB students in grades 3 through 8 take the Measures of Academic Progress (MAP) test. Taken by more than 6 million students each year, this test measures student growth and achievement in Reading and Mathematics.

Students take this assessment on a computer. If a student answers a question correctly, the next question is more difficult and vice versa. This means that we can gauge a student’s achievement more accurately, more frequently, and more quickly. Most important of all, we can measure actual progress by comparing students’ scores from one year to the next.

This table compares ISB’s mean RIT scores for reading and math to the mean RIT scores in US schools. ISB consistently ranks above the 90th percentile in math compared to other schools, and above the 80th percentile in reading (an accomplishment when one considers that only a third of our students are native English speakers).
